PDE5 inhibitors can improve drug-assisted erections after nerve-sparing prostatectomy and may support earlier recovery, but evidence that they restore unassisted baseline function after stopping is mixed.
Why rehabilitation is discussed
After prostate surgery, nerve signaling and spontaneous erections can be reduced for months or longer. Reduced oxygenation and inactivity may contribute to structural changes, creating interest in early erectile rehabilitation.
Keep the indication and the outcome separate. Evidence that a medicine improves a questionnaire score, blood-flow marker, or symptom during active treatment does not automatically show permanent recovery, disease prevention, or benefit in people without the condition studied.
What daily tadalafil achieved in REACTT
In a large randomized trial, daily tadalafil improved drug-assisted erectile-function outcomes during treatment and reduced penile-length loss compared with placebo. After a drug-free washout, unassisted erectile-function recovery was not significantly better than placebo.
A plausible mechanism is not the same thing as a proven patient benefit. The stronger the claim, the stronger the clinical evidence should be.

Why timing remains debated
Some randomized and pilot studies suggest earlier PDE5-inhibitor use may shorten time to recovery or produce better outcomes than delayed treatment. Protocols differ, and surgery quality, age, baseline function, nerve preservation, and cancer treatment all matter.

A pill may not be enough
Rehabilitation can include vacuum erection devices, injections, counseling, pelvic-floor work, and management of urinary incontinence or body-image concerns. A urologist should tailor the plan.

What “protecting the penis” should mean
Claims about preserving length, oxygenation, or tissue should be tied to actual trial outcomes. They should not be converted into a guarantee that daily tadalafil prevents permanent ED.

Cancer care comes first
Rehabilitation decisions must fit surgical recovery, cardiovascular health, cancer status, urinary symptoms, and other treatments. Do not start preoperative or immediate postoperative tadalafil from an affiliate article.

Frequently asked questions
Does daily tadalafil guarantee recovery after prostatectomy?
No.
Is on-demand treatment as effective as daily rehabilitation?
Some trials found advantages for daily treatment during active therapy, but long-term unassisted recovery remains uncertain.
When should rehabilitation start?
The surgeon or urologist should decide based on the procedure and recovery.
